Abstract :
[en] In this thesis several aspects of beyond SM physics schemes have been treated. In particular, two categories of models have been considered: ($i$) models with extra Higgs ElectroWeak (EW) doublets (multi-Higgs-doublet models), ($ii$) models with new fermion EW singlets (type-I seesawmodels). In the first category, two problems associated with the most general two-Higgs-Doublet Model (2HDM) and with the three-Higgs-Doublet Model (3HDM) have been tackled. In the former case the scalar mass spectrum has been derived in a basis-invariant fashion whereas in the later, after introducing a general procedure for the minimization of highly symmetric potentials, the minimization of an $S_4$ and of an $A_4$ 3HDM has been analyzed. In the second category, the possibility of envisaging seesaw-like models yielding sizeable lepton-flavor-violating decay rates has been investigated. With the models at hand, the corresponding charged lepton-flavor-violating phenomenology has been studied focusing on rare muon decays, for which forthcoming lepton-flavor-violating experiments will be able to prove large parts of their parameter space.
